[Ryan Sleevi, 2015/02/03 01:44:51]

Is there no way to move all this test data into secondary files to make it
easier to maintain/update?

[pneubeck (no reviews), 2015/02/03 20:15:00]

I assume that you mean adding files that contains exactly these byte sequences
in raw.
I could probably do that with an XHR but only if they're relative resources.

Wdyt?

[pneubeck (no reviews), 2015/02/04 20:59:20]

changed to XHR loading local files.
